Indeed, subsidence can cause gas and water pipelines to break right where they enter houses. Satellite images show hot spots where ground movement is taking place.
It thus allows a targeted replacement programme: the maintenance strategy has now become focused on areas of higher risk. Instead of replacing pipes and connections in a single district pipes serving individual houses or streets can be replaced. The result is better investment of resources by the pipeline operators and less risk to consumers from gas leaks or disruption from major water leaks.
